More work than I’d care to handle. I’m sure I’d be halfway into something like that and have to call in the support team.

I know what you mean, but this is actually very simple job, now rebuilding the front hubs have me nervous

I just noticed your winch mounted under the bumper in your photo. Do you have anymore pics or info on how you mounted it. I've seen them mounted above the bumper, in front of and now yours tucked in below.

Better check your fly wheel bolts, ours were not tight

The Cat procedure for doing the valve adjustment mentions using the alternator or other engine accessory and a wrench to rotate the engine.

Hubs are easier than expected. Just get a hub tool made from an old cover if you can find one. While the valve covers off, how about that fuel screw?

TM says by turning the alternator pulley (which I wasn't able to do by hand, but was able to do with a big socket and ratchet).

Is there a post with instructions / pictures of this?

Hub tool. Procedure is to install everything and torque this ring down, then feel for backlash on the small hub gears. Ideal is with your fingers just feel ever so slightly the smallest amount of movement. Tight gears are bad, loose gears are bad. Getting the perfect shim pack is the hardest part. I try to use the least amount of shims to get there. Don’t quote me but I think you want 10 to 20 thousandths of lash.

perfect, thanks so much, can I rent that tool from you? I have 2 used hubs in stock, but I do not have a way to make the tool/hub in the photo

I can get some for you, but it hangs to low, we have dragged it a few times, we are going to move it up out of the way,

So this is just an old bowl-shaped cover, with the "bottom of the bowl" machined off to leave the ring?

thats what i wondered also

I got one from a member here for this purpose. Not sure how much to cut off so I haven't yet.

I think all you need is enough ring left to hold the four shafts for the spider gears. As long as you can hold the gears in place so the backlash can be measured/adjusted. R&R is required to change out shims each time you get it wrong, but it works good.

You can band saw cut the cover, plasma the cover, what you need is a way to hold the spider in and check the gear lash. If I had my lathe set up I’d cut a cover for you, but I’m a few weeks from making that happen. I had a friend bandsaw mine and he was kind enough to face it in a lathe. Only cost me a few beers. I can send you more detailed photos and measurements if you would like. This is a must have tool for your tool box and since you have spare caps then you should get one made. Or two and trade one off.

ok, I understand, I will get busy on this, and yes I would love to have the info/photos and measurements super please

Steve 6x6x6. Is the creator of this method. I asked him all the questions you all ask now, my turn to help. FYI the way mine is cut it needs shorter bolts as well.

 

[Adventure Driven]

awesome, thanks for helping
